Nice looking truck, Estoril on black is the most desirable and therefor most expensive 4.6is combo.

You'll want to run a Carfax, see if you can find any maintenance history as well. If the car has not had the transmission replaced then be sure you have $5k in a savings account for when it goes south.

Why the 4.8 steering wheel? Since the rest of the truck is stock, was it in an accident and the airbag went off?

Most importantly pay for an inspection at an authorized BMW repair center. There are a lot of potential issues with these trucks... Suspension, cooling system, valve cover gaskets, oil separator, transmission, driveline, the list goes on.

Good luck. If all checks out, make a strong offer and drive it home.
